bwrap-oci and docker: /usr/local/bin/bwrap-oci: option parsing failed: Unknown option --root

[mviereck]

How can I set up bubblewrap and brwap-oci to use them with docker run option --runtime=bwrap-oci?

I currently did some test runs with kata (--runtime=kata-runtime) and would like to try bubblewrap, too.

I've installed bubblewrapfrom debian repository and compiled bwrap-oci from github.
I've configured docker daemon to use bwrap-oci. I get the error message:

docker: Error response from daemon: OCI runtime create failed: unable to retrieve OCI runtime error (open /run/containerd/io.containerd.runtime.v1.linux/moby/bd13878d4dc6e0837f98ad12bdf4024b978b5e0b22709459ed74e095d7bb76cc/log.json: no such file or directory): /usr/local/bin/bwrap-oci did not terminate sucessfully: /usr/local/bin/bwrap-oci: option parsing failed: Unknown option --root
